spacecraft would be capable of approaching the asteroid, characterising it, capturing it, and then redirecting it to a final stable
orbit that would be closer to Earth and thus easier for astronauts to
reach.

orbit, dipping in and out of the atmosphere, and using that friction to
reach a circular
orbit 400 kilometers above the surface.
